Resolved! STM32WB10CC RF output stage design question
Hello, For a personal project, I am designing a device that receives GPS data and transmits the UTC time information to other devices over BLE. I will also be designing a device that receives the data and displays it. For this, I have chosen the STM3...
STM32WB55 Trace Configuration Issue - No Trace Data
I've been working with the STM32WB55 microcontroller and have been trying to set up 4 bit trace functionality (ETM, not SWO) for debugging. I've connected the trace pins according to the datasheet and configured them in the STM32Cube software.Specifi...
Cascading LPTIM in STM32WL55JC17
I'd like to know if it is possible to cascade two LPTIM in order to make a 32-bit counter. I'm implementing my main LoRa application with the sequencer but I need to have 32-bit hardware counter running continously in the background to count external...
Can't get ADC to work in HeartRate example on STM32WB15 when CFG_LPM_SUPPORTED is set to 1.
I've modified basic HeartRate project to run an ADC inside of the task. However this results in adc always returning 0. Sometimes whole application hangs. However when CFG_LPM_SUPPORTED is set to 0. Everything works fine. I've already created github...
Resolved! BLE Advertising Problem
Hello,I am working on a STM32WB55RG BLE Project and the problem is that about once in every 3 program that I upload, BLE doesn't work. After reupdating the BLE Stack firmware, it works correctly. I am using the BLE firmware v1.16.0.4. What could be ...
Resolved! STM32WL55 PWM doesn't have deadtime option
Hi,I'm working on STM32WL55JC board and run "TIM_PWMOutput" example that run 4 PWM channels with diffrence pulse width.I'm trying to add deadtime between the channels (following this hands-on video https://www.youtube.com/watch?v=rDaC2N-33Oo Minute ...
Resolved! What is the cause of LPTIM_WaitForFlag function resulted HAL_TIMEOUT in STM32WL MCU ?
I modified the LoRaWAN_End_Node sample program for measuring the external pulses input to the COMP1. I register a task in the sequencer and set up the timer in timer server. It is no problem to run a test task by just toggle the LED. When I initializ...
