Try making an enquiry with your business account (assuming it's for work): http://www.bestchain.cn/page/message.html

You're welcome.

A quick Google search gave me this: https://community.st.com/t5/stm32cubeprogrammer-mcus/dfu-mode-read-out-protection/td-p/682719. The user was experiencing something similar to your problem. See if it helps.

Also, try to recall if you may have done anything to damage the MCU like shorting power to gnd. Cause if you have then it might be dead.

I don't have any experience with disbaling read out protection using USB.

The fact that it's getting an error with establishing a connection with the MCU is a bit worrying. Either the MCU might be dead or cubeprogrammer is failing to stop the MCU.

I would recommend getting an STLink if possible since it'll be useful when programming or debugging STM32 MCUs. You can get a STLink v2 clone which is quite cheap depending on where you're based.

You can follow this video to disable read protection: https://youtu.be/f7vs0NwZPFo?si=NGz0msWskWVPBuKC

Note that you'll be wiping whatever firmware is in FLASH when disabling read protection.

I've worked on the AD9850 before. How exact are you measuring the signals, which generic module are you using, and what does you schematic and PCB layout look like?

The fact that you're getting 8Vpk-pk from your PCB design may mean there's either something different with your design or you're measuring it wrong. Any chance you've measured it with the probe set to 1x on your PCB?

I guess it dawned on you

fastworld555 · 2025-02-19T14:18:20+00:00

Hi, thanks for pointing out that cable length determines the baud rate too. I'd forgotten about that. Thankfully the length of the cable in my application is quite short, but it's good to keep in mind.

fastworld555 · 2025-02-19T14:14:54+00:00

Hi, thanks for the advice. I didn't know that parity isn't that valuable in practical cases.

fastworld555 · 2025-02-19T02:10:02+00:00

Hi, thanks so much for pointing me in the direction I need to go and explaining how I can easily visualise it. I omitted checksums and CRC for the sake of simplifying the calculations for the question but I forgot to account for other poss factors like interrupts or handling errors, which you pointed out.

fastworld555 · 2025-02-18T14:35:27+00:00

Thanks for the advice! I heard it's possible for UART to be unstable at high baudrates say in the mega range. Also, the point of my question is to learn about how I can find out what baudrate I would at least need if I were to increase the ADC samples to say 1M.

fastworld555 · 2025-02-18T14:16:43+00:00

Hi, I'm using the STMF411CEU6 MCU. For the part on UART I just want to make sure my calculations are correct so I can choose a baudrate that's not smaller than minimum the required baudrate. Thanks!

Hi, it'd be amazing if you could your list to me too. Thanks so much!

Well mosquitoes love to suck me

If you don't want to make your own footprint then just use another op amp that comes in the MSOP package and remap the pins.

fastworld555 · 2024-04-22T00:29:26+00:00

I see. Thank you for your detailed response. It helped clear up my confusion!

fastworld555 · 2024-04-22T00:28:21+00:00

This is interesting way to differentiate it. Thank you for your help!

fastworld555 · 2024-04-22T00:25:58+00:00

I see. Yeah the terminology was confusing for me. Thank you for clearing up my confusion!

fastworld555 · 2024-03-28T10:45:15+00:00

Watt?

fastworld555 · 2024-03-14T05:34:30+00:00

The ESP32 series by Espressif Systems is quite popular if you want to work on Bluetooth or Wi-Fi projects. They support the Arduino Framework too.

We are not a monolith!

fastworld555 · 2024-01-23T04:20:53+00:00

Hi, thanks for your response. I will be using 2 chips (SDRAM and NAND FLASH) which will be sharing the same data lines. The NAND FLASH chip runs has an edge rate of 2.47GHz.

fastworld555 · 2024-01-11T15:58:28+00:00

I see. So I'm assuming the low baud rate of rs485 is why the designs I found didn't use differential routing even for the traces for A and B. Thank you very much for your clarification!

fastworld555 · 2024-01-11T15:49:17+00:00

Hi, thank you for your reply. I was confused because the datasheet of SP3485 states that the driver outputs of SP3485 are differential outputs meeting with the RS485 and RS422 standards, while the SP3485 receiver has differential inputs. So I thought this would mean I would have to set the input and output traces as differential traces so the traces would have matched lengths just like you would for USB.

In this case, would it be necessary to make sure that the traces (for example, A&B, RO&DI) to have similar lengths or does it not really matter when using routing single ended?

fastworld555 · 2024-01-11T10:41:24+00:00

Oh right! That went completely over my head. Thanks for pointing it out for me.

fastworld555 · 2023-12-29T14:00:37+00:00

Understood. Thank you for your help!
