Sometimes things move faster than expected. As someone with an embedded background this caught me by surprise: Tera-Byte microSD cards are readily available and getting cheaper. Heck, you can carry ten of them in a credit card pouch. Likely to move to the same price range as hard disks ($20/TB). That means that a 2+ square inch PCB can hold a 64-bit processor and enough storage for memo...

Jonathon - I'm in the testing phase now but, thankfully, strictly 32 bit code. One trick I've found that's been helpful is "fasmarm", which is an offshoot of a 386 et.al. assembler. The name is, if memory serves, flat assembler or fasm. I've got it on a Microsoft xp msdos directory. The fasmarm handles the 64 bit codes which might make it useful for you. Hul Jonathan Harston

I used a simple driver for serial port in Linux with success in many projects, but recently I found an issue with it. The scenario is an embedded Linux (running on iMX6) that runs a QT application (that creates a GUI on a touch display) and a C application that communicates over a serial port. When QT application starts some complex graphics (I see its CPU load reaching 70-80%), the ...

Many times I need to pass to functions or serialize an array of bits. If they are just a few (8-16 bits), I decide to use a standard array: uint8_t my_short_array_of_bits[16]; void abits_set_bit(uint8_t *array, size_t size, uint8_t nbit); uint8_t abits_get_bit(uint8_t *arrray, size_t size, uint8_t nbit); It sometimes occurs that the number of bits is much greater, maybe 100 or 200. If ...

I'm working at a system, where a server manages multiple PCIe data acquisition cards. Each card has its individual serial number available in the extended PCIe configuration space. The cards are controlled as UIO devices. Unfortunately, it appears that the card are sometimes enumerated in the random order. Proper management of the system requires that there are symlinks created with names permane...

The internet is full of posts from people tearing their hair out trying to use this tool :) I have it running OK although 99% of it is a mystery. And the code which the configurator generates is crap ;) With the old ICEs one could do a bar graph easily, across the address range, and then you could zoom in. Obviously there is no identical way to do this because the 32F runs code fully ...

I have an half-duplex RS485 bus with 10-20 different nodes. Some of them are 8-bit MCU based, one of them could be Linux embedded. It's half-duplex, so it's important for the transmitter node to disable the driver as soon as the last transmitted bit is shifted out. Many small low-cost MCU has interrupt on transmission complete, so the delay of disabling the driver is usually on the ord...
