I am using STM32L152. It goes into a standby mode and uses RTC to wake up every 10 seconds to carry out some tasks. Now, I would like to add an external interrupt (external switch) to the existing codes. In this case, the uC will exit the standby m...
When I compile and download the code. I see a USB problem.What could be the possible solution ?
Hi,I'm trying to implement a basic SPI full-duplex between two STM32.I have set up an F769I as Master, which works just fine. However the F446RE Slave doesnt transmit anything.I used CubeMX to create the project (file attached).The Master currently d...
Cube 1.18.0 appears to generate HAL CAN code in can.c and can.h which is aimed at the 1.21.0 redisigned CAN driver.The code refers to member variables which do not exist in the 1.18.0 register structures, for example: hcan1.Init.SyncJumpWidth = CAN_S...
Hi,We are sending confirmed messages. Every once in a while, we do not receive a confirmation from the gateway, which is fine. However, sometimes we are not seeing the callback in the ST LoRaWAN stack being triggered as expected. I expect the lack of...
Hi!I've bought STM32L082 for development and installed Atollic TrueStudio but couldn't find L082KZ MCU (the nearest similar is only 082CZ). How can I use this IDE or Keil is the only option?
Hello,I just test some interrupt stuff with Nucleo F439ZI and found that simply setting optimize to -Ofast leads to a timer 2 interrupt (compare event when generating a PWM) firing two times, while -O0 shows the expected behaviour. I test this with a...
Hi there. I'm trying to generate a Pwm signal using my nucelo board but I'm having issues doing this using cubemx. I've configured the clocks and oscillator based on resources I've found online but I'm not too sure what the clock source should be. I...
Hello everyone, I try to disp float value on TFT Screen with STM32F429ZI. But, sprintf function is not work. Can you help me ? please.float fff = 0.85; char s_TextMsg[20]; sprintf(s_TextMsg,"%.2f",fff); snprintf(s_TextMsg,20,"%.2f",fff);...
hey there,I bought me STM32 ST NUCLEO-L432KC for getting more into ProgrammingMicrocontrollers.In School i have already Programmed an ARM Coretex M3 Development board.There i had a Manualwith descriptions of the Controllers Registers, and how they ar...
