First a question:

I notice that in this forum almost all are using PICs. (I love PICs btw).

Does anyone here use other processors? in particular SuperH???

 

Nobody?

How about self programming or running programs from RAM? Anyone?

 

Not everyone uses PICs.
I use Atmel, Freescale and ARM.

 

I've used several different ARM parts, namely Freescale Kinetis, Energy Micro and STMicro. I too have noticed that this forum is kind of focused on PICs.

 

If you follow the threads on AAC you will notice a lot of the posts are from newcomers, students and hobbyists and there are few professionals. But that's ok.
The buzz these days are PICs and Arduinos so it is no coincidence that that is what people are inclined to use when starting out. For example, the PICAXE was very popular awhile back.

I wonder how many on AAC are working with a DSP56Fxxx or STM32Fxxx or similar?

I almost started using the Freescale Kinetics but then I discovered the STM32F407. So far I've been blown away!

 

I am using the SuperH SH7709S now which is a 32 RISC

Does any of you have experience on how to run a program from RAM. I mean, I have a program in ROM (flash) and want to copy it (or at least some functions) and run it from RAM

(the goal is that this part in RAM rewrites all the other parts in flash)
