Posted on March 29, 2012 at 22:09I am putting together a little self-programming bootloader. It looks to me like you program two bytes at a time, by putting the address in to the FLASH_AR and setting bit 0 in the FLASH_CR register. The manual doesn'...
Posted on March 29, 2012 at 18:24The product literature and feature table in the datashee (page 12), all seem to say that Ethernet MAC is only available on 100 pin (and upwards) STM32 F2 devices. However, looking a bit further down the datasheet, it...
Posted on March 29, 2012 at 21:32 Hello, I'm trying to get the CAN Example ( http://www.keil.com/download/docs/asp) to work properly, but I have problems with the RX and TX interrupts. When the message was sent and is pending in r...
