Posted on July 07, 2017 at 04:46Hi There,I am using STM32F429ZI discovery board to write an UART and LTDC code.I have Entesla serial to USB converter connected to the Discovery board via TTL(I am not using RS232).Simple use case is -Display the char...
Posted on July 06, 2017 at 21:02Hi,My stm32 board has four uart ports. Each of them is connected to rs 485 transmitter (tx only).I'm looking for any ideas how to extend my project to have more than four uart ports - up to 10.My first idea was to con...
Posted on June 23, 2017 at 09:26Its very strange to me .. I tried to recognize the problem by checking all datasheets information and search for same situation in the net, but unfortunately I find nothing .. please help me.the base issue is when i r...
Posted on July 06, 2017 at 15:00Designing own board based on stm32L0x1 and looking at debug provision.Am I right in thinking that printf style output is not available via the debugger ( ST-LINK/V2) on the stm32L0 (m0+) parts as:-1) They only have SW...
Posted on July 06, 2017 at 13:26Hi there,As mentioned above, I need to operate STM32F2 at 2.5V and the peripherals which i am gone use are USART, I2C, FSMC, ETHERNET, USB_FS. I have seen the datasheet for limitations depending on operating power sup...
Posted on July 06, 2017 at 14:44I encountered a problem in stm32F7xx_HAL_CAN.c.In HAL_CAN_RECEIVE_IT, the resource remains locked because it is missing __HAL_UNLOCK (hcan)#stm32f7-fw-1.7.0-hal_can_receive_it()-problem
Posted on June 09, 2017 at 09:26I am using cube 4.21 with a STM32F205 CPU.I configured the clock to run at 120 Mhz (25Mhz crystal M=20, N 192, P 2) in the file system_stm32f2xx.c generated by cube, I have the following:uint32_t SystemCoreClock = 160...
Posted on July 06, 2017 at 13:31Hello,The STM32 device I'm using has a 64 pin package.TIM1 is used for PWM control of a PMSM motor in FOC mode., connecting its 6 channels to a three phase IGBT bridge.I don't remap TIM1, so PA8, PA9, PA10, PB13, PB14...
Posted on July 06, 2017 at 04:17Hi, all! I want to program single byte to internal flash, but the standard peripheral library only support 'word' and 'half word', is it possible to program single byte, please?For example: mailto:0x11@0x08010000, ...
Posted on July 06, 2017 at 08:20Hi,We are using STM32F207VET6 microcontroller.We are requiring 2 SPI ports for different peripherals. Some SPI port pins are captured by ethernet, JTAG etc.so I can not use them. Following SPI signals I have configure...
