Posted on June 20, 2017 at 00:07 I've been working on a board based on the STM32F3 with a large number of ADCs and other peripherals. I'll also be using multiple I2C and UART peripherals; the responsiveness of I2C and UART is much higher than the...
Posted on November 06, 2015 at 04:33 I am using interrupt based UART IO (no DMA). HAL_UART_Transmit_IT function sets EIE bit in CR3 register. According to STM32F407 datasheet (and real behaviour), this generates interrupt only in multi buffer...
Posted on June 16, 2017 at 02:07Hi there, Has anyone been considering migrating from the STM32F4 chip to the upcoming H7 chip, and how involved\possible that process might be? My specific chip is the STM32F4ZIT6, but I'm curious about others' experi...
Posted on June 16, 2017 at 15:23HiWe have designed one system where we are using STM32F407 as the Master uC and STM32F103 as the slave(individual board) uC. Now our system is such that there are several slave (50 slaves) connected ot the master on ...
Posted on June 19, 2017 at 10:31We are using the STM32L432KC and we are facing problem to start the MCU.To sum up the situation : * The MCU can't start-up after a power off. **In order to reproduce the case you can use the nucleo L432KC -> y...
Posted on June 20, 2017 at 17:23BOR_LEV and RDP fields seems to be duplicate: both appears in option bytes and in FLASH_OPTCR. Are they alias to each other? If option bytes and FLASH_OPTCR differs in these fields which setting is applied?Can Option ...
Posted on November 28, 2016 at 10:59Hi, I'm using STM32L476RG microcontroller and I'm configuring the RTC to get the instant time value. I'm using LSE with 32,786 KHz as a clock source for my RTC . I have followed this application note (http://www.s...
Posted on June 20, 2017 at 16:36 Hi everybody, I've got a custom made board with STM32L486VG on it. I'm trying to do a RTC calibration with external 1Hz clock based on http://www.st.com/en/embedded-software/x-cube-rtc.html. Everything is set...
Posted on June 20, 2017 at 13:40Hi,I'm using STM32L1, and I would like to read out the option bytes values to make sure I was able to lock the read option of the memory.What is the quickest way to do so ?Thank you.
Posted on June 20, 2017 at 14:23Hi Everyone,I want to use the STM32F427VIT6 controller with four SDRAMs (IS42S86400D) and I would like to get some information of schematic and layout design. The address bus would be connect directly. Data bus would ...
