Posted on April 23, 2018 at 12:59I am using STM32f070xB controller. I want to use @TIM16_CH1 for input capture.GPIO_PIN: ♯PB8Timer clock freq: 3MHzTIMER is getting interrupted continuously but after 120Hz, flow is not going into Capture compare call...
Posted on April 25, 2018 at 13:51With I2Cx->CR2, I can send START, slave address, and so on. If there is NACK from the slave after slave address, MCU stops transferring and sends STOP. I want to keep sending bytes even when there is NACK from the sl...
Posted on April 23, 2018 at 08:54I used ST supply STM32_AN4502_FW_V2.0.2 for SMBus.When test Read Byte command?0x19 can work?but 0x00 can not ACK right,TIMEOUT happen,Why?#smbus
Posted on April 23, 2018 at 18:08I am currently using a driver that uses latch and clock signals to send special commands before sending data. For the sending of the data the driver works as for an SPI but with the signal of clock. Here is the diagr...
Posted on April 24, 2018 at 10:53Hi,I am planning to use STM32F301K8 with UFQFPN32 package (the PCB space is critical).I am going to use:1 or 2 UARTs in Asynchronouse mode driven by DMA. 8N1 . Boud Rate 115200 .1 or 2 SPIs driven by DMA. Csn by not ...
Posted on April 24, 2018 at 11:40Hello Friends!I am very new to STM coding and starting with the basics. I am using a STM32L011 uC and IAR compiler.I am trying to measure voltage from a sensor that is dumping analog data at about 5Khz. The ADC value...
Posted on June 27, 2016 at 16:07Just thought I'd save people some time if they are trying to get the CRC engine on the F4/F7 to produce the same results as most online calculators. If you are using CubeMX to configure your CRC, you need to specify t...
Posted on April 24, 2018 at 17:35I came across a rare issue where a previously failed flash operation would cause a subsequent operation to fail as well. I tracked it down to stm32f4xx_hal_flash.c::HAL_Flash_Program()When the function calls FLASH_W...
Posted on April 24, 2018 at 10:13Hi,I'm trying to set the UART baud rate to 600 on a Nucleo F070RB board to communicate with the CS5490 chip. (https://www.cirrus.com/products/cs5490/)I've only managed to go down to 732 baud rate. Anything below, it ...
Posted on March 25, 2018 at 16:45Hello, I have question about CAN on STM32F429-DISCO board.I found that CAN1 is shared with display control and CAN2 with on-chip debugger. In comments for this video (/external-link.jspa?url=https%3A%2F%2Fwww.youtube...
