| 59 | 1 | # Replacement front panel for the HP/Agilent 34970A - firmware |
| 2 | ||
| 3 | This repository contains the firmware for the replacement front panel for the | |
| 4 | HP 34970A acuisition unit described | |
| 5 | [here](https://whatever.sdfa3.org/hp-34970a-data-acquisition-unit-part-5.html) | |
| 6 | ||
| 7 | It is based on the [Mbed-os](https://os.mbed.com) framework and uses the | |
| 8 | [platformio](https://platformio.org/) development environment. | |
| 9 | ||
| 10 | Make sure to have this later properly installed (I suggest you install it in a | |
| 11 | Python 3 virtualenv). | |
| 12 | ||
| 13 | The firmware has been developped using platformio version 5.0.3 and Mbed-os 6.2. | |
| 14 | ||
| 15 | ## Compilation | |
| 16 | ||
| 17 | It should be a simple matter of calling: | |
| 18 | ||
| 19 | ``` | |
| 20 | (pio3) ~/p/p/hp34970disp$ pio run -e fp_dfu | |
| 21 | [...] | |
| 22 | Advanced Memory Usage is available via "PlatformIO Home > Project Inspect" | |
| 23 | RAM: [== ] 21.4% (used 14048 bytes from 65536 bytes) | |
| 24 | Flash: [== ] 22.9% (used 90040 bytes from 393216 bytes) | |
| 25 | ========================================== [SUCCESS] Took 28.13 seconds ========================================== | |
| 26 | ||
| 27 | Environment Status Duration | |
| 28 | ------------- -------- ------------ | |
| 29 | fp_dfu SUCCESS 00:00:28.129 | |
| 30 | ========================================== 1 succeeded in 00:00:28.129 ========================================== | |
| 31 | ||
| 32 | ``` | |
| 33 | ||
| 34 | Note: the `platformio.ini` provides 2 similar environments (`fp_dfu` and | |
| 35 | `fp_stlink`) which are identical but the `upload_protocol`. | |
| 36 | ||
| 37 | ## Uploading the firmware | |
| 38 | ||
| 39 | You can upload the firmware either via the (USB) DFU mode or the SWD/STLink | |
| 40 | port on the PCB. Note that the USB socket on the PCB does not power the board, | |
| 41 | so it must be already powered (which is typically when the board is connected | |
| 42 | to the main CPU board of the HP 34970A). | |
| 43 | ||
| 44 | In order to be able to upload the firware by DFU, the STM32 MCU on the front | |
| 45 | panel must be booted in DFU mode, which can be done by pressing the DFU button, | |
| 46 | then the RESET button while keeping the DFU pressed. | |
| 47 | ||
| 48 | The STLink upload method does not need the board o be booted in DFU mode. | |
| 49 | ||
| 50 | ``` | |
| 51 | (pio3) ~/p/p/hp34970disp$ pio run -e fp_dfu -t upload | |
| 52 | ``` | |
| 53 | ||
| 54 | or | |
| 55 | ||
| 56 | ``` | |
| 57 | (pio3) ~/p/p/hp34970disp$ pio run -e fp_stlink -t upload | |
| 58 | ``` | |
| 59 | ||
| 60 | ## Credits | |
| 61 | ||
| 62 | THis firmware uses a modified version of the [UniGraphic]() library and the | |
| 63 | [QEI]() library. | |
| 64 | ||
| 65 | ||
| 66 | ## Notes (deprecated) | |
| 67 | ||
| 68 | Use mbed 6 | |
| 26 | 69 | |
| 70 | For some reason I had to disable mbed-client-cli/ (multiple definition of `cmd' error at | |
| 71 | link time). | |
| 72 | Put a .mbedignore file in: | |
| 73 | ||
| 74 | $ cd /home/david/.platformio/packages/framework-mbed@6.51504.200716/features | |
| 75 | $ cat .mbedignore | |
| 76 | mbed-client-cli/* | |
| 77 | frameworks/mbed-client-cli/* | |
| 78 | ||
| 79 | see https://docs.platformio.org/en/latest/frameworks/mbed.html#ignoring-particular-components |
