Posted on May 08, 2013 at 14:48 Hey all, I've been trying to get SPI working on my STM32F3 discovery board recently but it just doesn't seem to be working. I was hoping to test it in loop-back configuration and display the sent data on the board...
Posted on June 05, 2013 at 07:47Hi! I'm using STM32L152 + IAR6.5. EEPROM writing/erazing routings are placed in RAM. Interrupt vector table and critical interrupt handler too. I need to write EEPROM and serve critical interrupt at the same time. Bef...
Posted on June 06, 2013 at 03:42How long does it takes the STM32F303 to change an input from pull-up enabled to pull-down enabled? How long does it take to change an input from pull-up enabled to pull-down enabled? It seems that if I read the inpu...
Posted on June 06, 2013 at 00:05All my timer interrupts are working except for TIM1. What could be wrong. I'm using Keil ARM with the STM32F013C8. Here is my startup code: EXPORT WWDG_IRQHandler [WEAK] EXPORT PVD_IRQHand...
Posted on June 04, 2013 at 16:59Hi all, I just want to clear up my understanding of DMA and how it works with respect to communication peripherals such as SPI and I2C. First, let's say I have a function that does some matrix multiplication and saves...
Posted on June 05, 2013 at 15:41I'm looking to order a 32-bit microcontroller to replace my atmega168. Whatever I order needs to have at least 2 quadrature decoders, and it would be great if it had an fpu, but that's not necessary. Also, I'm looki...
Posted on May 16, 2013 at 18:53I have a project where I will need to flash a few hundred chips that are already on boards. I have set up a chain programmer which is controlled by an MCU. basically it is just a chain of sockets for the boards that al...
Posted on June 03, 2013 at 20:11i want to drive a motor for a control of the door following the LDR sensor signal ( open when it feel light and close it when it's darkness)I have an STM32F100RB. please i need your help urgently thanks a lot
Posted on June 04, 2013 at 18:38Good afternoon, I'm a student working on a robotic project using a STM32F3 discovery evaluation board. I read that there are several IO that are 5 volts tolerant among all IOs the board have. The issue is that I can't...
