Posted on October 08, 2015 at 17:35 Hi, I'm working with stm32f4-disco. I made a code that works well: the micro waits for an external interrupt, and when receives the interrupt it makes pulses of 40kHz with a duration of 1 ms. Now, I wanted...
Posted on October 07, 2015 at 15:53Hi all, I am using a STM32F103 chip where USART1 and USART2 are connected to Smartcard units. I have tried to communicate to the Smartcard by first sending a reset signal (according to ISO 77816 definition) and the...
Posted on October 02, 2015 at 22:06Hi there. Thanks for the STM32Cube software. I have a Discovery board and would like to try some USB-OTG testing, but there are only USB demo apps for the EVAL board, is it possible to port them so they run on the...
Posted on October 02, 2015 at 14:39Using HAL, I have configured DMA1_CH2 and USART3_TX such that once in a while, a block of bytes will be copied from memory to peripheral, in NORMAL, i.e. non-circular mode. Now, my handler, HAL_USART_TxCpltCallback...
Posted on October 04, 2015 at 17:07 Hi all, I am not sure about a DMA config for DAC on STM32F2. Could you please tell me if I made an error using 8bits words with this DMA config? Especially with DAC base address? #define BUFF...
Posted on October 08, 2015 at 11:44 Hello. There's an issue in MBED's spi_api.c file. Function void spi_frequency(spi_t *obj, int hz) line baud_rate = __builtin_ffs(divisor) - 1; The problem is this line makes a...
Posted on August 11, 2015 at 12:00Hello,I'm using nucleo-l053r8 for my project. I have to make a data logger application with a sensor. Here i have developed my code in mbed tool. I also store the values in SD card. Now my task is to make my own cus...
Posted on January 30, 2013 at 15:17Hi, we have a problem with the STOP mode of the STM32F3. We have the feeling, that the F3 immediately returns from STOP mode, if ANY interrupt is enabled and has been activated before entering the STOP mode. The se...
Posted on April 24, 2014 at 11:34Hi All, I am designing the Heat Meter with STM32L053 now. So have you released STM32L053 Standard Peripheral Library yet please? It is very important to speed up our design schedule. Thanks. #stm32l053
Posted on October 01, 2015 at 09:30hiPlease see the attached file.I use STM32L151QE PA0(WKUP1) for external wakeups from Standby Mode, CASE1 is wakeup OK, but CASE2 is wakeup NG.I know WKUP1=High and entering standby, then the device will not wake...
