This week, we have continued to research component for our devices. We analyzed more precisely features and made the decision to keep the following items:
| µC | STM32F215RG |
| BLE | nRF52832-QFAA |
| LoRa | SX1276IMLTR |
| Wifi | CC3220MODASF12MONR |
For each component, we chose a microprocessor development board to begin the software part of each device. We ordered all microprocessor development board Friday and we will receive them on Monday. We ordered the following items:
| µC | OLIMEX STM32-E407 |
| BLE | Nordic nRF52 DK |
| LoRa | ST B-L072Z-LRWAN1 KIT DISCOVERY |
| Wifi | Texas Instrument CC3220SF-LAUNCHXL |
Nordic nRF52
I got the BLE development Kit from Nordic last Friday and I began to use it. I read a lot of information about this board on Nordic website.
I read, more specifically, information about the nRF52_DK PCA10040 v1.1.1 which contain a nRF52832 component. I got back useful files like datasheets, SDK, examples, etc.
I started to set up the environment to this development board. I got back a linker script and wrote a gdbinit to load and debug a program on the nRF52_DV. I’m editing a Makefile able to compile, load and debug a program.
Next week I will finish the environment and start to reorder useful file to push in our git repository. I would like also to discover the PCB software Xpedition PCB to start to design schematics.
