LPC17xx HAL_LLD, GPT, PAL, RTC, SERIAL drivers

Postby marcinj7 » Wed Jun 12, 2013 8:27 am

Hi,

Zip file contain LPC17xx drivers:
hal_lld
gpt
pal
rtc - not supported counter increment interrupt
serial - only uart0, not supported dma

Testhall for rtc and irq_storm.
I've made some changes in chrtclib.c for LPC17xx RTC.
Tested on LPC1766.

Thanks Marcin,
I'll try and get that in the main branch soon.

Finally got around to merging these drivers into the main tree.
Also includes a LPC17xx CAN driver...
Thanks to Marcin for his work on these.

Excellent work, there is some impressive support for LPC17xx now.

Have you considered porting the code to version 3.0? I am going to switch the trunk to the 3.0 branch in a couple weeks, the new code could be officially released in 3.0.

One interesting thing in 3.0 is that the HAL is able to work with both RT and Nil kernels but potentially also without an RTOS (bare metal mode) or potentially with other RTOSes complete enough to implement the OSAL layer. This feature alone makes an HAL implementation even more valuable.

I was hoping to use the move to 3.0 to re-structure the LPC tree, something like the way the STM32 tree is arranged.
Do you have any notes on the changes required to port to V3.0?

Good point, I will write a small 3.0 porting guide before switching the repository.
