Re: [GSOC] Project update

easier to implement, and it would not matter which GPIO peripherals each BSP supported. Alan On Tue, Jun 17, 2014 at 10:52 AM, Andre Marques mailto:andre.lousa.marq...@gmail.com>> wrote: On 06/17/14 15:39, Alan Cudmore wrote: Hi Andre, I checked out the your GPIO_API

[GSOC] GPIO API

Hello, The GPIO API has been updated with doxygen documentation and code comments, along with a blog post that explains the current API work flow [1], and another blog post explaining how the API can be tested using the Raspberry Pi [2], both containing links to the actual code. Currently thi

Function pointer within isr

Hello, I am trying to call a function through a function pointer from an interrupt handler, but I am not sure if this is even possible as the system hangs at that point. If not, is there any way in RTEMS to have that function executed outside the isr? Thanks, André Marques. ___

[GSOC] GPIO status and I2C start

Hello, The Raspberry Pi GPIO interrupts are already working, and a test case is available to test that [1]. A function is also provided to debounce a switch if needed. The test case requires two switches and two LEDS using the same setup described at [2] by only changing the pin numbers. The

Re: [GSOC] GPIO status and I2C start

becomes important to have that info. For instance, the I2C interface on the P1 GPIO header uses different pin numbers for model A and model B/B+. Alan On Sat, Jul 5, 2014 at 6:58 PM, Andre Marques mailto:andre.lousa.marq...@gmail.com>> wrote: Hello, The Raspberry P

Raspberry Pi BSP SPI bus

Hello, The Raspberry Pi SPI bus on the P1 GPIO header is already working, both through polling and interrupts on the bus FIFOS, and has been tested with a microchip 23k256 SRAM device. The bus code can be found in: https://github.com/asuol/rtems/blob/GPIO_API/c/src/lib/libbsp/arm/raspberrypi
