Posted on August 06, 2015 at 23:29I've got an STM32L151RET6. This is a category 5 device. My understanding from the manual is that the on board EEPROM is in a separate bank (0x08080000) so that writes will not block reading from program flash. Howev...
Posted on August 31, 2015 at 15:30I'm working with a microcontroller stm32f215. This device have a wheel of time (single encoder) connected to PF8 pin - TIM13_ch1. How best to accomplish reading this time round? Using the capture? Using the interrup...
Posted on August 06, 2015 at 16:41HelloI am using NUCLEO L053R8 (STM32L0) , Keil uVision 5.15 and ST-Link (embedded in the nucleus board). I let CubeFx a FW program using CubeFx with HAL enabled.All compiles wellI can use the the blocking transmit f...
Posted on August 05, 2015 at 19:29Hello all,I am using the ADC1 regular conversion or ADC1/2 dual-mode regular conversion to acquire a video signal. The dual-mode is used at higher frame rate. In both case, I am using the DMA. This part is working...
Posted on August 06, 2015 at 15:20Hi. I'm using STM32F107VCT6 in a project. I need to remap the SPI1 signals to pins PB5 PA4/5/6. when i send the data from SPI1, i see the waves of MOSI but cannot see the wave of SCKL (PA5). why cannot see the waves...

Posted on August 31, 2015 at 07:49 hi every body i have a problem with strstr function, i receive characters from uart with interrupt & save them on the n length array(buffer array), then in main loop i check buffer with strstr funct...
Posted on August 28, 2015 at 22:56HI guysI can simply not see why this is not workingvolatile _Bool DitOn = 0;volatile _Bool DahOn = 0;void HAL_GPIO_EXTI_Callback(uint16_t GPIO_Pin){ BSP_LED_Toggle(LED1); if(HAL_GPIO_ReadPin(GPIOI,GPIO_PIN_2) == GPI...
Posted on August 18, 2015 at 07:18I have been trying to use the latest HAL drivers, make thing easier once you understand their complexity. I am up to trying to get the I2C port working. i have no activity on the I2C bus at all the pins remain high ...
Posted on August 30, 2015 at 20:03Hi, as specified in the topic, I'm trying to create my own wave file player using f4-discovery board. I've managed to configure the DAC, read the file, find the data section, read the samples and I can hear the soun...
