Hi,
I have a nRF24LE1 development kit and a starter kit. If I turn the power off and turn the power back on using the power switch S9 on the motherboard. The nRF24LE1 chip does not power-up. I need to press the reset button S10 before the chip works as expected.
Can anyone explain this behaviour? I would like the chip to startup immediately after it is powered.
I would like to have the chip work as a dongle with a coin battery only.
In the product secification says the following:
Power-on reset The Power-On Reset (POR) generator initializes the system at power-on. It is based on an RC network and a comparator, as illustrated in Figure 50. For proper operation the supply voltage should rise monotonically with rise time according to the specifications in Table 112. on page 177. The system is held in reset state for at least 1ms after the supply has reached the minimum operating voltage of 1.9V.
How can I achieve the monotonically rise, when using a switch?
