| * 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 * | |
