I've been trying to test the time to digital converter max35101 with an stm32f407vg6 microcontroller and am stuck for some reason. The timings for the SPI communication seem to be extremely strict for this device and with the stm32 chip i have available without an external crystal, correct communication seems impossible. For example from the time the CS line goes low i only have 40ns (max) for the clock line to start pulsing. My setup takes at the very least 3-4us. Is this something that could legitimately make the communication impossible. Max35101 chip should trigger an interrupt after a particular opcode but i haven't managed to achieve that yet.I know my question may seem stupid, as the datasheet states the maximum timing clearly, but i would like a second opinion on this.
thanks
thanks
