Notebook:
25.09.2010: Proton Compiler version 3.5.0.6.
21.08.2013: The code for the periodic timers written for <Whisper> is
superior to all previous implementations. So this should be applied to earlier
firmware.
23.09.2013: Periodic timers and random functions applied in <Ice2> for Laura Maes.
31.07.2014: The code for the displays contains a mechanism to let the four PIC's communicate with each other, using busy and acknowledge signals. This code also makes use of multiple main program loops.
21.04.2015: Compiler upgrade performed. Proton version 3.5.7.1 now. Proton24 compiler (version 1.0.2.8) installed as well. [ www.protonbasic.co.uk ]. Previous code needs some minor changes such as removing Reserve_Ram 256 and the High_Interrupt_Start and High_Interrupt_End lines in the IRQ driver code. Also the new compiler version does not support dword operations in an interrupt handler.
11.09.2015: The manual states an incorrect upper value for the PWM frequencies as set with the HPWM command. Further remarks in the source code for <Tinti> hub.
12.04.2016: Changing the PWM frequency changes the PWM values on both channels.
08.06.2016: Implementing different analog input channels is well implemented in the Chi_Mot firmware. Proton Compiler version is now 3.5.8.1
24.06.2016: Key pressure command applied on note repeats is well implemented in the source for <pp2>, <Flex>-blade bending processor.
01.08.2016: For the PIC24 and dsPIC33 microcontrollers we are using the Proton24 compiler ( Version 3.6.0.2) with a PicKit3 programmer.
10.12.2016: The code for the <Bug> generator is a nice prototype for a monophonic synthesizer using variable sampling rate for tone generation.
19.02.2017: The code for <Pi> uses a full digital approach to 3-channel waveform synthesis with ADSR.
21.03.2017: The code for <Rodo> e-drive implements a 12 bit sampler as well as full digital audio power output.
04.04.2017: The code for <Rodo> radar has gesture recognition implemented as well as full buffered midi merging. It also uses the external interrupt feature.
29.05.2017: The code for Thunderwood's storm wind controller is a good prototype for a 3-phase ac induction motor controller.
31.08.2017: The code for Balsi, version 1.0 is a generic 50Hz 3-phase induction motor controller.
10.09.2017: Suspicion of a SWORD implementation bug in the Proton24 compiler. (cfr. dev. of code for 3 phase motorcontrol)
18.10.2017: All 18F2525 processors can be replaced with 18F2620 types.
24.10.2017: The compiler no longer supports the MIN and MAX functions.
03.05.2018: The hub board for <Pos> has a nicely working motor controll for a monophase asynchronous motor.
09.12.2018: The <Balsi> motor control board has frequency measurement and PID for the large siren pitch control.
10.12.2018: Newest version of the Proton compiler ordered from Crownhill. Newest manuals downloaded as well.
18.12.2018: Compiler version 3.6.2.7 (Proton8) and 1.0.5.3 (Proton24). The Proton8 compiler now gives problems with our IRQ coding replacing HSRin and HSRout. The code for Balsi hub is the new supposed to be compatible version for use with the new compiler version. First tests on the oscilloscope looks like it's working again...
15.01.2019: The <Balsi> robot is the first one using only the newest compiler versions.
24.09.2019: Serious problems in getting our multitasker to work with the compiler upgrade. The Balsi trick doesn't seem to work when applied to the 18F4620 damper board for Tubo. Adding a single HRSout instruction in the code appears to be a condition for the serial-in procedures to function.
06.11.2019: Compiler upgrade downloaded. Proton8 is now version 3.7.3.1, Proton24 is version 1.0.6.4. So far, it does not seem to entail source code changes.
08.12.2019: A small change in the coding, but a great improvement on timing precision: see code in the new timer0 interrupt handling for 8-bit PIC's. (example: all Tubo boards) With this code, timing jitter is less than 5 promille. (average jitter is ca. 5us , worst case jitter occuring rarely is 200 us). This coding change also applied to the velo/hold boards on our <Pos> robot.
11.12.2019: Compiler upgrade performed. Proton8 is now version 3.7.3.3 and Proton24 version 1.0.6.6. From now on, if we want HPWM to work on two channels, we have to add declares in the config file!
Declare HPWM1_Pin = PORTC.2
Declare HPWM2_Pin = PORTC.1
12.12.2019: Firmware for Whisper rewritten.
08.02.2020: Firmware for <Flut> is a very good example for a driver for robots. Same principle applied in <So>, version 3.
15.02.2020: Firmwares for Autosax 16-bit pics spread
the load over two processors, with simple data exchange between chips. However,
this did not fully solve the problem of the glitches we seem to have.
03.05.2020: New mono-synth board made, also using two processors, for experiments
and research. This board, october 2020, used for the hunting horn in the <Rumo>
robot.
06.10.2020: Board and firmware made for roaster motor in <Rumo>. We had a 22uH inductance in the Vcc+ analog lead, but this caused oscillations! 100uH cured the problem.
08.10.2020: There seems to be a limit in the nesting of if-then constructions in Proton24 code. <Rumo>-roast code with if-then in the midi-parser does not work. We must use a select-case construction apparently. Ramping works nicely now in this code.
09.11.2020: Switch debouncing, using sampling in the low IRQ and a shift register is handled very well in the code for the horn-motor in the <Rumo> robot. Look into the firmware for the mercury switch version. This is now the <Hunt> robot.
07.12.2020: A bug plaguing almost all code we wrote using
the 24EPxxxMC202 processors solved: to read a combined 32 bit timer, first the
lsb should be read (time.word0 = TMR2) , than the msb via the hold register:
(time.word1 = TMR3HLD). Firmware for <Hunt> , <Bug> and <Pi>
newly uploaded.
12.12.2020: New implementation for ADSR on 24EPxxxMC202 chips: using tmr2 as
sample frequency generator. So far, applied to <Hunt>,<Autosax>,<Bug>,<Flut>.
To be done for <So> as well.
15.12.2020: Applied to <So> as well
17.12.2020: Major rewrite of the 3-channel code for HybrLo. Now at version 2.0
23.12.2020: Three new test and debug boards made for 18F and 24EP series microprocessors.
These new boards have 5p DIN midi connectors for in and out, as well as an on
board power supply.
24.12.2020: Compiler upgrade: now Proton8 version 3.7.3.6
and Proton24 1.0.6.7. At first sight, no changes in the source code seem required.
Soldering...
19.01.2021: Firmware for the pitch chips (24EP-series) updated on <Flut>,<Hunt>,<Autosax>,<So>,<Bug>.
Vibrato is now reliable on all of them.
10.03.2021: PIC firmware still to be uploaded in
the 24EP chips on the following robots (cfr. bug cured 07.12.2020): Tubo (motors),
Rumo (motor), 2-Pi, Balsi, Pi, Mirrored-X, HybrLo, Rodo (sensor and e-drive),
Thunderwood (Storm), Aeio (parser and radar). The source code is allready upgraded.
01.04.2021: Start coding for <RorO>. Finished
july 2021.
30.06.2021: <Trumpeter> finished. Delayed
vibrato implemented.
10.10.2021: <Cornalto> finished. Note attack

o.k. with the latest compiler
03.11.2021: Compiler upgrade. Proton8 has become
Positron8 and Proton24 became now Positron16. Required changes: 'Optimiser_level
= 3' has to become DECLARE Optimiser_level = 3
12.01.2022: Coding for <Steely>: here we implemented dead-times after
pulses to protect duty cycle restrictions.
13.01.2022: Shouldn't we start studying and using the dsPIC33FJ128GP802 This
exists in 28 pins DIP, has 12 bit ADC and 16 bit DAC (stereo) on board...
06.02.2022: MPLAB upgraded.Now we are using version IPE
and IDE 6.00. Previous version was 3.35. The new version supports the PICkit4
programmer, which we also bought and installed.
20.03.2022: 10 16 bit PIC's for <3Pi> programmed and tested o.k.
16.05.2022: 18 16 bit PIC's for <4Pi> programmed and tested.
11.11.2022: Further work on 3-channel synth code for hooters in Rumo.
26.11.2022: Firmware for the Melauton PIC's upgraded. (10-bit PWM and better
motor control algo). This code no longer uses Gosub's but has procedures and
functions instead.
15.12.2022: Firmware for <Troms> redesigned. Now also with dead-times
after pulses.
20.03.2023: New hub board made for <Kazumi>. Firmware o.k. with Positron
compiler.
