Posted on March 12, 2018 at 16:31Hi, I am having a problem using COMP1 on a STM32l496 chip. I am doing a proof of concept on a Nucleo board. I'm using a signal generator to put a 1KHz sine wave on the IN+ pin, and I'm using the DAC as the IN- s...
Posted on March 31, 2018 at 00:35I am trying to construct a CubeMX based version of the LwIP_HTTP_Server_Netconn_RTOS project in the repository. I have used the board selector in CubeMx of the H743i-Eval and setup the options for the hardware to ma...
Posted on June 08, 2017 at 17:31 Edit: OK so just for the record, I guess, I replaced HAL_I2C_Master_Transmit_DMA() with HAL_I2C_Mem_Write(), which seems to be the appropriate command for what I'm doing, and that is working fine. One questi...
Posted on April 01, 2018 at 17:04I have a PCB made for 100 pin F407. Is there a STM32F6 series CPU which works in that PCB? There seems to be a lot of 100 pin F6 CPUs. Is there something I should know, especially if I make a new PCB fit for both.#st...
Posted on April 01, 2018 at 01:27Hi,guys! I need your help, please. How to turn on off four leds on the board of stm32f4 by sending a character using serial communication (example : if I send 'A', blue led is on. Send 'B', orange led is on. Send 'C...
Posted on April 02, 2018 at 11:26Hi, I have a STM32F0C6 board and I'm trying to use RTC function with LSE.It seems RTC is working correctly and I can check the waveform of LSE Clock from MCO pin.But when I check the waveform of OSC32_IN and OSC32_Ou...
Posted on April 01, 2018 at 20:14The pin voltages are too high on my board. The (nominal) 5V pin measures 6.8V, and the 3v3 pin measures 4.7. The board appears to be running normally.I am powering the board via USB (CN1) JP1 is OFF. JP3 is set to U5...
Posted on April 01, 2018 at 11:25Hello everyone, I had a question about how to run IRTIM on STM32F030. If there is an answer please tell me how to solve it?
Posted on April 02, 2018 at 10:53I want to use a STM32F103C8 as a standard NTSC color video out source. Arduino has a black and white video library that is compatible with most of thier boards. I figured the vastly more powerful STM32 could manage f...
