Kommentar zu Using the USART von Stefan

Hallo, to my knowledge, the STM32 Discovery does not support flashing through serial line. The IFLAT-32 has this option, but since I don't use windows at all, I only know how to flash the IFLAT-32 from Linux. The Discovery could be flashed through JTAG or the build in stlink. I think, one could get OpenOCD with the stlink working on Windows too, but again, I don't know much about windows, and I don't know if CooCox has OpenOCD integration. Regards

Dear Sir,

Can you suggest me how to flash the file serially ie from uart. I am using CooCox IDE on Windows 7.

With Regards.

So this library file is the API file, that i’ll replace to the one i have? I just have basic start up files minus the configuration. which one is your spi?

Hi, libemb I developed some time ago includes a almost complete library for the nRF24l01+ and its various modes. It also includes operations to easily preset the different modes, they could be found here (look for the "nrf_preset_*" methods). Within the methods, you will find the register settings. Example usage could be found in the tests. Regards, Stefan

I’m working with the MSP430 and nRF24l01+ and I need help getting started with its set-up I have all the libraries for it including API, SPI, URART, and main.c. The ting is I’m not sure how to set up the payload or the air data parameters. Can you please help

Hmm, should work with 80MHz. In general, baudrate should be calculated like this:

USART1->BRR = ((2 * clock) + baud) / (2 * baud);

Note: We round() the value rather than flooring it, for more accurate divisor selection.

And as I remember “clock” should be set to the freq. of PPRE2.
