The new dsPIC33CH parts have a 6 cycle divide whereas the older dsPIC33F takes 18 cycles. The number of cycles is not data dependent. So I guess more Silicon for fewer cycles, but used how? Cheers -- Clive

I usually have a static buffer and I don't want to use a dynamic buffer. char buf[BUFLEN]; I have to construct a long string, and it is quite easy to call snprintf multiple times: int n = 0; n += snprintf(&buf[n], BUFLEN - n, ...); n += snprintf(&buf[n], BUFLEN - n, ...); n += snprintf(&buf[n], BUFLEN - n, ...); n += snprintf(&buf[n], BUFLEN - n, ...); I was convin...

This hit the news yesterday: SQLite contained a remote code execution bug. According to the ZDNet article the bug has been fixed as of v3.26.0 released December 1st. If your application uses SQLite, you may want to look into updating it. https://blade.tencent.com/magellan/index_en.html https://www.zdnet.com/article/sqlite-bug-impacts-thousands-of-apps-including-all-chromium-based- browse

Nowadays the poor embedded developer faces new challenges that go outside the limited world of C/C++ program on a resource constrained hardware. Now the hardware isn't so resource constrained (Raspberry and many other embedded Linux boards or SOM are just examples) on one side. And the device isn't isolated anymore, it is usually connected (directly or indirectly to Internet). The Th...

For a test setup, I have created a small UI using the serial port connected to a VT100 capable terminal (Tera Term). I use the VT100 commands to create a "nice" (for certain values of nice) looking output. This works OK. But now I periodically (every few seconds) have an amount of data that needs to be stored on the PC. A CVS like output with a 100 lines or so. I can just spit this out aft...

What do you really use for embedded projects? Do you use "standard" makefile or do you rely on IDE functionalities? Nowadays every MCU manufacturers give IDE, mostly for free, usually based on Eclipse (Atmel Studio and Microchip are probably the most important exception). Anyway most of them use arm gcc as the compiler. I usually try to compile the same project for the embedded target...
