Posted on May 28, 2015 at 20:23I want to enter the Bootloader on STM32F429 Discovery and reprogram the internal flash via I2C. I read AN2606 and then connected the following pins from my I2C master: SDA <-> PB9 SCL <-> PB6 GND <-> GND BOOT0 <-> 3v I...
Posted on June 02, 2015 at 08:42Hello,this is targeted for STM32F4xx developers for standard peripheral drivers.You did a great job when you add defines for new libs only included in F446 by using/* For example: STM32F4xx QSPI: *//* stm32f4xx_qspi.c...
Posted on May 29, 2015 at 15:33I am trying to interface a pair of XBees with a pair of STM324x9I-EVAL boards to open up a wireless communication link. I'm considering using the microUSB breakout board to interface with the dev. board but am unsure w...
Posted on May 26, 2015 at 23:26 I have an F103-Nucelo, Kiel, and want to set Tim1 with PWM on Ch2,Ch2n,Ch3,Ch3n. I have this set as correctly as I can see in STM32Cube. I have a scope and can verify the Ch2/Ch3 work perfectly. The complmenet/neg...
Posted on May 30, 2015 at 04:14 Hi, when dealing with SPI with DMA this works: SPI_CS_on(); if (HAL_SPI_TransmitReceive_DMA(&hspi2, &dataout, &input, 1) != HAL_OK) { /* error */ } while (HAL_SPI_GetState(&hspi2) != HAL_SPI_STATE_READ...
Posted on May 06, 2015 at 12:06Hi at all,I'm using a STM32F4 (with HAL libraries) and I have configured the USB as device in order to realize a communication wit the PC through the virtual COM port.When I send the first packed (from PC to MCU) I hav...
