Posted on June 16, 2015 at 03:49 (I managed to fix this as I was writing this post) STM32CubeMX 4.8.0 was generating the incorrect prescaler value for SPI3 after upgrading. .ioc contained: SPI3.BaudRatePrescaler=SPI_BAUD...

Posted on June 15, 2015 at 23:33Hello: This problem has me totally dumbfounded. Please see the attached image and screen shot of schematic. An absolutely simple circuit, yet it does not want to oscillate. This is the second board (different PCB, dif...
Posted on June 15, 2015 at 21:37I was surprised when configuring an I2C peripheral on my STM32L152QEH based design and realized that there was no support for SMBus? After selecting either SMBus-alert-mode or SMBus-two-wire-Interface on the pinout t...
Posted on June 12, 2015 at 21:59The STM32F429 has three ADCs: ADC1, ADC2, and ADC3. They all have a status register, which has an EOC bit to indicate conversion complete.There's also a common status register (ADC_CSR) shared by all three ADCs that c...
Posted on June 15, 2015 at 14:20Hello, I am trying to configure the SPI3 port of an STM32L151UC micro controller. I have tried several things but I see no output on the related pins. When using gpios instead of the AF of the SPI peripheral, I can ...
Posted on June 12, 2015 at 14:20I would like to connect to my car's CAN network but I'm a little confused as there are two CAN interfaces in STM32F407 - CAN1 (Master, PB8 and PB9) and CAN2 (Slave, PB5 and PB6). Why do we need two interfaces? Can you...
Posted on June 01, 2015 at 11:27 I made a project with stm32cude mx for stm32f401 discovery, discovery board is usb msc host, send a command to devide (usb msc device) then receive data form device my project connected and saw all infomati...
Posted on June 15, 2015 at 10:26Hi,I am using STM32F405.The NRST pin is connected to Vdd through a 100k pull-up resistor and to GND with a 0.1uF capacitor, just follows the design of STM32F4-Discovery. The NRST pin is also connected to GND with a 2-...
Posted on June 15, 2015 at 10:41 Hi, Using the cube 4.8.0 I configured PA2 to be GPIO_EXTI2 because I want an interrupt generated when the signal connected to that pin goes low but the code that gets generated for me looks like this: /*Configure G...
