Anybody have experience of BT modules with CCS, especially the new RN4020?
I do now [16 months later].

I can't recommend RN4020, folks... At least not with its current 1.23 firmware (released in ...

Folks,

I've noticed that standard string functions ( strncmp(), for example) take longer to execute when one of the parameters is a constant string stored in Flash. I have the pass strings in RAM ...

I'm a big fan of our terminal program SIOW. But I can't seem to figure out how to send an ASCII string terminated with carriage return (CR). When I type 24 24 24 into Hex send and press enter, the C ...

Nevermind. It was a hardware problem. Nothing wrong with my timer code.

You, folks, are always an inspiration.

Folks,

I’m trying to use the Timer0 as a tachometer to keep track of a fan. I can see the square wave on the RA4/T0CKI pin with the oscilloscope. But the counter doesn’t seem to be incrementi ...

Folks,

Does USB 2.0 (and PIC18F4550 in particular) require termination resistors? Here's what I've found so far.

USB 1.1 does require terminating resistors (like the 27R in
Any suggestion, in ...

As you probably already know,
giving a different function type to the second level functions by adding a dummy argument is a workaround for the
present example.
Yes, I have thought about dummy pa ...

Colleagues,

Here’s an example, where compiler suspects that the there may be recursion and generates an error “Recursion not permitted (function_name)”. But, the recursion doesn’t actually ...

I'll second Embedded C Programming and the Microchip PIC by Barnett, Cox and O'Cull

It had compiled with the change, which you've proposed.

At first, I thought that this change would undermine this use case. The order of the bit fields should corresponds to that in a register of ...

Colleagues,

This compiler error (or lack of feature) has come up in the past. For example in typedef union // AD7794 status register (read only) bit fields. See Table 16 in & ...

Ttelmah, you are spot-on. By default, most interrupts are enabled including new_data_int (aka conversion_complete). When I've disabled them and re-enabled only the tap interrupt, all worked as exp ...

Obvious response to your comments: Please don't assume that I'm stupid. Do me such a favor.
... and you're always welcome to post something that is not completely useless. That is, less useless th ...

Folks,

By any chance, does anyone have a code snippet, which would show how to initialize BMA180 accelerometer for tap sensing? Doesn't matter whether it's SPI or I2C, I should be able to adapt it ...

I want to have an array of structs. It would be nice if I could make it a const, but that not required. I think the following initialization should work. At least it compiles.

struct
