Posted on February 19, 2017 at 01:32Sorry if that's known but I've only learned today that on eBay you can get a board which tries to look like stm32f4discovery while it's only a copyon eBay they list it as 'Stm32f4 Discovery Stm32f407' (spelled wit...
Posted on February 19, 2017 at 12:41Hi At the moment I am using Keil with one of the STM32 cheap development boards. I have the free license (well, until Feb 2018) for the STM32F0x and L0x chips. I am using this becuse I am new to the system and a...
Posted on February 09, 2017 at 14:23Hi. I'm using the HAL_GPIO_EXTI_Callback function to have an event when a pin is falling or is rising.To know if a pin is low or high I use this functionif (__HAL_GPIO_EXTI_GET_IT(GPIO_Pin)== GPIO_PIN_RESET) {} el...
Posted on February 14, 2017 at 11:51Hi All,I am using GTS-511E2 fingerprint module and i want read data through I2C. According to fingerprint module datasheet we need to read EEPROM register value, which i have read successfully.Now next part is re...
Posted on February 16, 2017 at 23:07 I am trying to make RC522 (RFID) work on STM32F0 discovery board. I read the arduino library which can be useful, before starting I am trying to make SPI work. I have connected all the pins to STM32F0 and CS p...
Posted on February 17, 2017 at 12:11Hello,I'm using STM32F407 and i want to trigger an injected ADC1 measurement by Timer 1, Capture Compare Channel 4.So:Timer 1, Channel 4 is configured as Output Channel with a timebase of 50us. So each 50us, I got...
Posted on January 31, 2017 at 16:30Hi All,I m trying to use I2C on STM32F104. Here is my init code. I am not able to read an EEPROM. To test I sent data (I2C_SendData(I2C2, (uint8_t) 0x100);) in a loop (with a small delay), and monitored SCL and SDA...
Posted on January 02, 2017 at 11:21 Hello, I have a strange a strange behaviour using the spdifrx hardware on my STM32F769I-DISCO. I want to receive the IEC60958 subframes from the hardware but I get the data only without the preemble and all ...
