Hi! I'm planning to automatically test a reasonably simple board in an embedded system. The tests cover functional requirements of the firmware. Unit testing is not needed (it's already done). The module under test talks to a 3 other boards via SPI and serial. It has a few sensors and relays connected. All external boards and sensors will be simulated by a software test bench running...

Hi, all. My custom board has a LPC2368 installed and runs FreeRTOS. What I am trying to do is to invoke bootloader in ISP mode from my application - to allow in-field firmware upgrade, when FlashMagic tool will be used. I referred the NXP appnote AN10356 to get a clue of how to do it. What I changed in the example given by the appnote, is the use of GPIO pin P0.14, since the silicon use...

Hi, I am developing a data transmission circuit using the Cypress EZ-USB development kit. I have a question about setting register. When I unenable a certain pin, for example, CLKOUT pin, it have to be 0 Voltage, I think. But although the CLKOUT pin become to be float, it still outputs 2.5 Volt. Is it correct? Or, because of wrong firmware I made, it become to 2.5 Volt, not to 0 Volt? I am ...

I'm not an expert on test-driven development. I know the general ideas behind TDD, however I never used it in my projects. I want to start using TDD, at least creating some unit testing on some more critical units. However I have many difficulties. For a module that calculates a checksum, it is very simple to create a unit test. However an embedded firmware is more complex. Consider...
