Hi, I am using sprintf to format data before sending it over a UART. STM Cube IDE 1.16.1STM32F103 The code works in one project but not in another. I have ticked "Use float with printf in MCU/MPU Settings"int size = sprintf(&Buffer,"{\"src_addr\":\"%...

Hi,I'm usingSTM32CubeIDE 1.6.1Windows 11I can get PWM working using both TIM1_CH1 and TIM2_CH2The frequency and duty cycle are as expected from the settings in the IOC file.However, when I try and do a HAL_TIM_PWM_Stop_DMA(htim, TIM_CHANNEL_1);I get ...

Hi,I am generating code using STM32CubeIDE 1.16.1Example SelectorBoard Name - NUCLEO-U083RCADC_MultiChannelSingleConversionThe code compiles and runs.Any change then made to the IOC file appears to delete at 34 files one file is still needed - stm32u...

Hi, I have a program running on a STM32U083RCT that is raising a HardFault when running at full speed, but when stepping through the code using a debugger the code appears to run correctly. I have a transceiver device connected to to USART2. I have a...

I'm running a GPS application based on @Tesla DeLorean application that he kindly shared here:https://github.com/cturvey/RandomNinjaChef/blob/main/f746g_disco_gps.c I'm now encountering a HardFault When I step into the function to load the register v...

I have rebuilt the project from scratch, must be something in the setup that caused an issue, perhaps I somehow put the buffer in an area that was not RAM.Either way the code above does work correctly.

I have managed to format with a string I will try with an integer tomorrow.However, as mentioned this same line of code works correctly in a different project.

Thank your for the response to this post. I have successfully used your code to driver the WB2812.RegardsJorgie

Hi Pedro,My apologies, you said "I don't use HAL for such things." Which I assumed meant you use LL.I'm interested to know what you would use and where I would start with this. I am keen to understand how to drive the manual if it is going to produce...

I have found one issue with the code provided above, the numbers being used to change the pulse width are completely wrong for the timer set up. I have since changed for (int i=11; i>=0; i--) { if (color&(1<<i)) { pwmData[i] = 66; } els...
