That's enough, because technology is only one of the pillars of your future, and it is not the biggest pillar, unless you are willing to be an old engineer![3] Do not be a technical master, but a general quality master!

To view the system clock with the oscilloscope, the system clock is output to the MCO pin.After one night, I saw the waveform.First, create an empty project. Code Comment out:; Import systeminit; Delete systeminit write RCC initialization function by yourself; LDR r0, = systeminit; Blx R0The following is a setup function that uses HSI as the system clock. If the PLL is not practical, the HSI is directly output to the MCO pin:Void my_rccinitmcohsi (voi

the multimeter is normal, and whether the waveform produced by the oscilloscope measurement is correct ~~ Unfortunately, I still cannot use the oscilloscope --! This debugging process should be quite painful. If you don't talk about it, you will naturally know it when debugging ~~ Summarize the work required for the next hardware task ~~ 1. Normal power supply 2. Normal clock 3. correct register configurat

watch the oscilloscope in the corner! Skills other than technology are more important! From ancient times to the present, the United States and Japan are all like this![4] Make Friends of the social education community! Do not interact with engineers only, think that there is a common language, but more importantly, communicate with other people. If you want to be a boss or a senior manager one day, these are the people you face throughout the day. U

The peripheral circuit of the chip is very simple, so it is very easy to use.Previously, we used TB and tssop packages. This time, we use the GB and sop6. It is basically the same as the 10-40 TB version.The debugging should have been smooth, but the driver has been delayed for a long time.Symptom:After connecting to the computer, you can find the device. But an exclamation point is given. The error message "Windows cannot load the driver required for this device, causing this device to work abn

is used, for example, if we transmit a five-digit red, then our M4-M0 bit is connected to the opposite side's P7-P3, the P0-P2 of the other party is connected to our M4-m2 (this can be verified by an oscilloscope ); For the above interface, each driver usually has a unified interface, for example: Open, close, ioctl, write, read, MMAP, of course, different drivers may only be implemented. For LCD drivers, the most important thing is open, ioctl, and
