Hi, I would like to read AT Command responses back from my ESP2866, as I want to check whether the response is "OK" or "Error". I made a function as below but it doesn't work properly.The plan is to send AT commands on USART3 and right after that, re...
dear all,My question is about the Cortex-M0+ options that were selected for the STM32G0 products (table 1-1 from the ARM Cortex-M0+ TRM). I can hardly find them in the STM32G0 RM and DS. Do you know where I can find the answer ?Regards
HW situation is:I2C2_SCL on PB10 (pin L4)I2C2_SDA on PB11 (pin M4)Both have a pull-up resistor of 18K.The sensor attached to these lines is removed, so nothing is connected.This is not a dev-board but our own design.I have generated code through STMc...
Hi ST,I'm trying to enable PWM mode of Timer14 (STM32F030C8T6). But the output is always LOW. I do all the steps described in the ST Periferal Library. Also I successfully run the similar code on STM32F103xxxx. Could you check this simple code? Is th...
We are using the STM32H745 dual core MCU in the we are trying read and write the data using DMA. When we are trying to receive the data that controller going to the DMA error call back function ,for this what may be the issue . And also in interrupt ...
Hello,I'm using STM32f411RE with ADC and I would like to know why when the sampling time is less than 84, I don't find by calculation the same expected conversion frequency/time?My calculation is Tconv = (3+12)/210000Hz = 714 ns so a frequency of 1.4...
Hi!I am using STM32F373RCT6 on custom board. I am working from scratch on SDADC.I have configured SDADC1 Channel 6 to read the voltage in polling method but it is not working. I am sending .c files for your reference to check configuration. After ca...
Hello All,I am attempting to utilize the SDMMC port on the STM32F7 to transfer large images from external SDRAM to an attached SD card. I am currently doing this successfully at 5 FPS. I want to speed it up to 10 FPS, but I am having unreliable delay...
Hello,I have 3 boards with STM32F205RBT using 2xDAC and 9xADC. Two boards are working just fine but one board has the second DAC output inverted (write 0 ->3V, write 4094 ->0v). The same program is used, boards are the same. The DAC output is amplifi...
