STM32WB55CGU6 Zigbee WindowCover
Hello everyone, The last few days I have been trying to get Zigbee working on my STM32WB55CGU6 and I can now switch on and off a light! But the more difficult thing to get working is the WindowCover. Below you will find the image where my STM32 has c...
ADC sampling shows wrong values after wakeup from STOP2 mode (STM32WB55VGQ)
@ABN Hello All,Steps happening in the code (FREERTOS based). 1. Initialization ( 4 ADC channels, DMA, BLE)2. Take 1 sample of each channel. Store in register.3. GOTO STOP2 mode.4. Wakeup at 10th second using LPTIM.5. Reinint everything above menitone...
STM32WB55 and "Proper" way to send an array or struct over BLE to update characteristic.
I am working on a WTM32WB55RG BLE application that reads a sensor via I2C and sends the output of some calculations to a BLE characteristic running on the p2pserver on the same WB55RG. I'm able to successfully send an Integer to the BLE characterist...
Resolved! Cannot wakeup from STOP2 through EXTI
Hello everyone,I want to try to wakeup my system from the the STOP2 mode with a button press. The button is also in use in the rest of the application and works just fine. But when going to STOP2 it does not wake up the system again.I've tried it wit...
Error: No STM32 target found!
I think it is the most popular topic among STM32 programmers who use ST-LINK V2 programming devices.I have two devices: one is the Lora E5 MIni, and the second is the Lora E5Dev board. Both respond to the AT commands, so I expect they are healthy.A f...
