Posted on January 15, 2016 at 09:16Hello! I am using a STM32F302 custom made board. When I set TIM2, CAN_TX and CAN_RX at the same priority, CAN_TX and CAN_RX interfere with the performance and interrupt timer of TIM2. I checked the user manual and ...
Posted on January 19, 2016 at 23:54On stm32f072xb (Discovery board), I am able to detect an interrupt on PA0.Using the example provided, I configured the external interrupt as such. EXTI->IMR = 0x0001; /* (3) */ EXTI->RTSR = 0x0001; /* (4) */ ...
Posted on January 10, 2016 at 02:08 Hi everyone, I am trying to connect a nucleo board to an ESP8266-01WiFi board using UART1, I've used the STM32Cube to generate the project. I've added the NVIC and there is aUSART1_IRQHandler function g...
Posted on January 18, 2016 at 20:10 Hello, I'd like to create a sequencer on my STM32F100RB (@8MHz) to control 8 independants PWM channels. I configured a timer to generate a 10us interrupt wich call the update function. //timer 10µs...
Posted on January 12, 2016 at 16:22Hello. According to UM1907 I can power the board via ST-LINK USB connector (CN14) if the host PC can deliver 500mA. My board doesn't start using CN14 connector. When I power it from the same USB via usb_fs (CN13) o...
Posted on January 19, 2016 at 15:08Hi,I need to write on the backup registers when a falling edge is detected on PA0. So I put some capacitors on Vbat but now I need some advice to write the stmcube code. Then I have to be sure that the value stay i...
Posted on December 15, 2015 at 14:21 Hi all, trying to use the UART interrupt fuction, i set up cube and got a close look at theSTM32Cube_FW_F4_V1.9.0\Projects\STM32F4-Discovery\Examples\UART\UART_TwoBoards_ComIT this is my code, that does no...
Posted on January 19, 2016 at 18:35Hello everybody, I've configured with CubeMX the standard pinout of the STM32F429I-DISCO. In Cube I've added the USB_OTG_HS peripheral with Internal PHY set to Host Only. I've then activated the USB_HOST Class for ...
Posted on January 19, 2016 at 16:08 Hello, ST community! I'm developing firmware for a custom board (schematics not available) based on a http://www.st.com/web/catalog/mmc/FM141/SC1169/SS1575/LN9/PF250188?sc=internet/mcu/product/250jsp...
Posted on January 19, 2016 at 15:59Hello. I have some troubles when implementing PWM generation on the timer TIM1. I use STM32 HAL Library. I have to update the values of registers CC1�CC3 each time when TIM_UPDATE event happens. I planned to use 2 ...
