Posted on May 05, 2012 at 18:46I'm using STM32L151R8. I have SPI slave on SPI1 pins PB3-PB5 and CS on PA15. The SPI doesn't seem to work and i need to double check the warning about disabling the JTAG pins.But STM32L151xx reference manual has funny ...
Posted on January 03, 2013 at 20:25Hi. I know that the evaluation board have ~192k of ram , and 16mbit of external RAM, my question is how can i use the 16mbit of RAM,how do i ''tag'' variables to be allocated on the external RAM ? Thanks Michael
Posted on January 09, 2013 at 04:39 I have been working for a couple of weeks trying to simulate a simple assembly program using Keil uVision 4. I have tried the Cortex M3 for a target and I have tried a few of the STM32F10x devices for the targ...
Posted on January 10, 2013 at 04:48Hello, I'm using: STM3221G-EVAL board with Keil uVision V4.53.0.0 and supplied by MCD Application Team SDIO_uSDCard example software V1.1.0 to test operation of SDIO and micro SD card on the evaluation board. STM...
Posted on January 10, 2013 at 22:59 I would like to be interrupted every time an external input occurs - line is take n high on each data tran sfer to another chip. I can see the external input on the scope but I don't ge...
Posted on January 04, 2013 at 21:41Hi! I am using STM32F0DISCOVERY kit and so far tried to run one of the peripheral examples called ADC_DMA. Short example description: ''The ADC1 is configured to convert continuously Voltage reference and Temperatu...
Posted on January 10, 2013 at 00:58 I just got my hands on a STM32 and I'm quite new to MCU programming. I'm trying to implement a (seemingly) simple counter. I want to count up the pulses without being interrupted and be interrupt...
Posted on January 10, 2013 at 14:55Can I change the system bootloader program so that it can be customized according to my application (Actually I want the stm32 system bootloader to take HEX file from my external EEPROM and write it into controller...
Posted on January 10, 2013 at 14:57Hello *, I was searching for information on the protocol of the STM32F10*** buildin boot loader. But I can't find anything beyond buad rate negotiation. Except something like ''there is a GET ID command.'' What I f...
Posted on January 09, 2013 at 06:03I know this may be a silly question, so hopefully there is a quick answer: Im trying to configure one of the GPIO pins for a simple output. However when I measure the pin voltage, it reads 3v. Is there any way I ca...
