* Investing in training allows your team to be as productive as * | |
* possible as early as possible, lowering your overall development * | |
* cost, and enabling you to bring a more robust product to market * | |
* earlier than would otherwise be possible. Richard Barry is both * | |
* the architect and key author of FreeRTOS, and so also the world's * | |
* leading authority on what is the world's most popular real time * | |
* kernel for deeply embedded MCU designs. Obtaining your training * | |
* from Richard ensures your team will gain directly from his in-depth * | |
* product knowledge and years of usage experience. Contact Real Time * | |
